It's very difficult to imagine a 19.26 produced essentially in the second half of a race, while being even with others at the 100m mark. Blake winds it up very well between 70-100m in the straight 100m, I'm delighted he was able to stay in control for this run.

Do you remember Michael Johnson's face when he ran 19.32? Total surprise. He could hardly believe it.

Do you remember Bolt in Beijing? He strained all the way to the line, saw the time and threw his arms in the air. He was surprised.

Blake today? No surprise. He had what appeared to be a bad start, did not lead at 100m, then blew past the World Championship silver medalist who was running a lifetime best. And he wasn't even surprised.
